[Method] Comparative test of new maize cultivars was conducted at different altitudes in 2015, and the yield, main economic characters, agronomic traits, growth period and resistance of maize cultivars were analyzed. [Result] Ruidan 26 and Yongrui 16 can be cultivated in the areas below the altitude of 2 200 m; Huaxingdan 88 can be cultivated in the areas below the altitude of 1 750 m; the other new maize cultivars still need to be tested further. [Cenclusion] The research results can be applied in this area and other similar areas, which will effectively promote the upgrading of maize cultivars and improve the yield per unit area.展开更多
